 IfcCSV
 ======
 
-IfcCSV exports and imports data from spreadsheet or tabular datasets. This lets
-you view and edit IFC data using CSV, ODS, XLSX, and more.
+IfcCSV lets you view and edit IFC data using spreadsheets or tabular datasets,
+such as CSV, ODS, XLSX, Pandas DataFrames, and regular Python lists.
+
+IfcCSV lets you select rooted elements using the IFC selection queries. These
+elements may be physical elements (walls, doors, windows, etc), construction
+types (wall types, door types, window types, etc), or even non-geometric
+(tasks, resources, cost items, etc).
+
+Once you have selected a list of elements, you may specify attributes,
+properties, quantities, or relationships to extract and use as columns in your
+table.
+
+For example, you might use a selection query of ``.IfcDoor``, for all doors in
+your project. You may then specify a ``class`` attribute, a ``Name`` attribute,
+a ``type.Name`` relationship, and a ``type.Description`` relationship. This
+will produce a table as shown:
+
++------------------------+---------+------+-----------+------------------------------------+
+| GlobalId               | class   | Name | type.Name | type.Description                   |
++========================+=========+======+===========+====================================+
+| 3AjGVS9EjBeBrDA5_tAcwQ | IfcDoor | 01   | DT-A      | Single swing steel frame door      |
++------------------------+---------+------+-----------+------------------------------------+
+| 07BewvHLn2$x6HsHH06rAA | IfcDoor | 02   | DT-A      | Single swing steel frame door      |
++------------------------+---------+------+-----------+------------------------------------+
+| 3b3Mk8uIb3Qu_eSPKxsI8x | IfcDoor | 01   | DT-B      | Double swing steel frame fire door |
++------------------------+---------+------+-----------+------------------------------------+
+| ...                    | ...     | ...  | ...       | ...                                |
++------------------------+---------+------+-----------+------------------------------------+
+
+.. note::
+
+   IfcCSV automatically inserts the GlobalId column at the beginning, in order
+   to uniquely identify the element.
+
+This tabular data may then be exported in your desired format.
+
+You may then edit the data, and reimport the data back into IFC. The changes
+you make in the spreadsheet or table will also be made in the IFC.
+
+There are different methods of installation, depending on your situation.
+
+1. **Source installation** is recommended for users wanting to use the latest
+   code as a library or a CLI utility.
+2. **Using the BlenderBIM Add-on** is recommended for non-developers wanting a
+   graphical interface.
+
+Source installation
+-------------------
+
+1. :doc:`Install IfcOpenShell <ifcopenshell-python/installation>`
+2. `Clone the source code <https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.7.0/src/ifccsv>`_.
+3. ``cd /path/to/IfcOpenShell/src/ifccsv``
+
+Depending on which formats you want to edit, you will need to install more dependencies:
+
+- ``pip install odfpy`` for ODS support
+- ``pip install xlsxwriter`` for XLSX support
+- ``pip install pandas`` for Pandas DataFrame support
+
+Here is a minimal example of how to use IfcDiff as a Python module or CLI
+utility:

+
+    $ python -m ifccsv -h
+    usage: ifccsv.py [-h] -i IFC [-s SPREADSHEET] [-f FORMAT] [-q QUERY] [-a ARGUMENTS [ARGUMENTS ...]] [--export] [--import]
+

+      -f FORMAT, --format FORMAT
+                            The format, chosen from csv, ods, or xlsx
+      -q QUERY, --query QUERY
+                            Specify a IFC query selector, such as ".IfcWall"
+      -a ARGUMENTS [ARGUMENTS ...], --arguments ARGUMENTS [ARGUMENTS ...]
+                            Specify attributes that are part of the extract, using the IfcQuery syntax such as 'type', 'Name' or 'Pset_Foo.Bar'
+      --export              Export from IFC to CSV
+      --import              Import from CSV to IFC
+    $ python -m ifccsv -i model.ifc -s out.csv -f csv -q .IfcProduct -a "Name" "Description" --export
+    $ cat out.csv
+
+Here is a minimal example of how to use IfcCSV as a library:
+
+.. code-block:: python
+
+    import ifcopenshell
+    from ifccsv import IfcCsv
+
+    model = ifcopenshell.open("/path/to/model.ifc")
+    # Using the selector is optional. You may specify elements as a list manually if you prefer.
+    # e.g. elements = model.by_type("IfcElement")
+    elements = ifcopenshell.util.selector.Selector.parse(model, ".IfcElement")
+    attributes = ["Name", "Description"]
+
+    # Export our model's elements and their attributes to a CSV.
+    ifc_csv = IfcCsv()
+    ifc_csv.export(model, elements, attributes, output="out.csv", format="csv", delimiter=",")
+
+    # Optionally, you can explicitly export to different formats.
+    # ifc_csv = IfcCsv()
+    # ifc_csv.export(model, elements, attributes)
+    ifc_csv.export_csv("out.csv", delimiter=";")
+    ifc_csv.export_ods("out.ods")
+    ifc_csv.export_xlsx("out.xlsx")
+
+    # Optionally, you can create a Pandas DataFrame.
+    df = ifc_csv.export_pd()
+    print(df)
+
+    # Optionally, you can directly fetch the headers and rows as Python lists.
+    print(ifc_csv.headers)
+    print(ifc_csv.results)
+
+    # You can also import changes from a CSV
+    ifc_csv.Import(model, "input.csv")
+    model.write("/path/to/updated_model.ifc")
+
+Using the BlenderBIM Add-on
+---------------------------
+
+The BlenderBIM Add-on is a Blender based graphical interface to IfcOpenShell.
+Other than providing a graphical IFC authoring platform, it also comes with
+IfcOpenShell, its utilities, and a Python shell built-in. This means you don't
+need to install Python first, and you also can compare your IfcOpenShell
+scripting to what you see with a visual model viewer, or use a graphical
+interface to access the IfcOpenShell utilities.
+
+1. Install the BlenderBIM Add-on by following the `BlenderBIM Add-on
+   installation documentation
+   <https://blenderbim.org/docs/users/installation.html>`_.
+
+2. Launch Blender. Change to the **Scene Properties** tab in the **Properties
+   Panel**. Scroll down to the **IFC Collaboration > IFC CSV Import / Export**
+   panel.
+
+3. Browse to your IFC file.
+
+4. Type in a filter query, such as ``.IfcDoor``.
+
+5. Optionally add attributes you'd like to export.
+
+6. Press **Export IFC to CSV**
+
+TODO: add pictures and make this clearer for non-developers.
